Changing the preceding definitions can have a dramatic change on

operation. For example, switching a lathe from the standard ZX plane to

the reversed XZ plane causes:

G02 circular interpolation clockwise and G03 circular interpolation
counterclockwise to reverse. G02 becomes circular interpolation

counterclockwise and G03 becomes circular interpolation clockwise.

fixed cycle operation rotates 90 degrees. For example, on a lathe, a
normal straight threading operation that cuts threads in the Z axis rotates

to cut face threads along the X axis. The Z axis move becomes the

infeed into the thread.

other plane dependent features to reverse their operation.

Plane Configuration for Dual Axes

On single processing systems only the master axis name (first servo

configured in the dual group) can be used in a plane definition. On dual

processing systems, if an axis is a member of a dual group, slave servos

(any servo in the group other than the first one configured) can be used in a

plane definition. This plane can only be activated when the dual group is

decoupled.

If you’re defining two planes one of which includes a slave and another

axis and the other that includes the master of that slave and the same other

axis, then the master and the slave must either both be the first or both be

the second axis in both plane definitions. For example:

Axis 1 (X)
Axis 2 (Y)
Axis 3 (Z)
Axis 4 (W)

These axes are part of a dual group named Z

This configuration:

The following plane definition is invalid:

G17 XY

G18 ZX

G19 XW

Because Z occurs first in the G18 plane with X and its

slave Z slave W occurs second in the G19 plane with X.

The following plane definition is valid:

G17 XY

G18 ZX

G19 WX

Because Z occurs first in the G18 plane with X and its

slave (W) also occurs first in the G19 plane with X.

Incorrectly configuring this plane generates the error message “Dual Plane

Configuration Error” on the control once the AMP file is downloaded.
